摘要: 制备了聚合硅酸硫酸铝絮凝剂 其最佳制备条件为pH值5.5—6.O,SiO2浓度2.0—3.0%,Al/Si摩尔比1.0或0.5.X射线衍射分析说明Al2(SO4)3已参加了聚合物的生成.应用实验表明Al/Si摩尔比是影响其絮凝性能的最主要因素.该产品对于低浊高色度水的处理具有优异的絮凝性能.Abstract: PASS flocculant was prepared. The optimum conditions of preperation are pH=5.5-6.0, the concentration of SiO2=2.0-3.0%, Al/Si(molar ratio)=0.5 or 1.0. X-ray diffraction proved that Al2(SO4)3had reacted with polysilic acid and produced the non-crystalline polymer. The experiment for application shows that the Al/Si is the most important factor that affects the floc-culation efficiency of PASS. And PASS is very efficient for the water treatment that has low turbidity and high color degree.
